To all whom it may] concern Be it known that I, ELIJAH C; DAVEY, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented newv and useful Improvements-in Roller Bearings, of which the following is a specification.

The inventlon provldes a roller bearing specially designed for use in connectionwith heavy machinery but :which may be .adapted for general use. i

The inventlon consists of a bearing sleeve having itsend. portions oppositely tapered,

rings encircling the tapered ends of the hearing sleeve and having their inner facestaered or inclined at a differentangle to the inclination-of the tapered. ends of the bear ing sleeve, two sets of tapered rollers ar-l rangedlbetween the tapered ends of the bearin sleeve and the rings, .said tapered rollers eing connected by means of gimbal joints, retainers for the rollers, a barrel en circling the rings and ad usting means for such rlngs to maintain close fit between the several parts so as toprevent any lost motion or play.

. The lnventlon consists of'the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated-in the a'ccompanying drawings, and pointed out in' the a pended claim.

Ref

erring to the drawings, forming a part of the specification, Figure 1 isa central longitudinal section of aroller bearing embody ing theinvention'. Fig. .2 is an end view. Fi 3 is a section on the linearrror Fig. 1.

vt iorresponding and. like parts are referred to in the following description and indicated in all the views of the" dr'awings,\by the same reference characters The bearing sleeve 1 has its end portions oppositely in'clined,' the ta ered ends being symmetrical from a media line toward the extremities of the sleeve. Tapered rollers 2' are mounted upon the tapered ends of, the bearing sleeve 1 and are provided at their ends with journals 3. The inner journals 'of the rollers are connected by means of gimbal.

joints i-this being necessary because of the opposite inclination of the axis'of the rollers. By having the rollers of two setsjointed outward displacement is prevented and the roll? ers are held in a given-position. Rings sen--v compass the set of rollers. The outer side'of each of the rings is of universal diameter whereas the inner side inclines, the inclination being such as to correspond with the in- 'clination of-the elements of the rollers in' contact therewith. The inclination of the tapered ends of the bearing sleeve 1 likewise corresponds with the elements of the tapered rollers 2- in contact therewith.

By reason of the rollers being tapered it is understood that the opposing side?1 of the rings 5 and bearing sleeve 1 have a ifi'erent relative inclination A barrel 6 encircles the rings 5 and retains them in place. Diametricall disposed adjusting devices 7 are fitted to -t e barrel 6 to engage the outer ends of the rings 5 to admit of moving such rings inward to insure a close fit between the parts 1, 2 and 5.- The adjusting devices 7 are'hhown as wedges which are adapted to be secured to the inner side ofthe barrel 6 in any manner. to admit of their adjustment to efi'ect lateral movement of the rings 5.

T he bearing sleeve 1 admits of the roller bearing receiving a shaft, journal or like part and thebarrel 6 provides forthe adap} tatioii of the roller bearing to the .hub of a wheel or other part. Retainers. 8 are fitted to the journals of'the rollers and assist material ly in holding the rollers in place, such retainers beingin the'form of rings.

From the foregoing description, taken in connection with theaccompanying drawings, the. advantages ofthe construction and-of the method of operation will be readily apparent to those skilled in the art to which "the invention appertain's, and while, I have described the principle of operation'of the.

' invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown in merely illustrative,pand that such changes maybe made when desired as are within the'scope of the claim append.

ed hereto.

' Having thus described the invention whatis claimed as new is sleeve, rings encircling-the rollers and dis- A roller bearing comprising a bearing g sleeve, rollers vmounted upon" the bearing posed in spaced relation one to the other and each provided with an inwardly beveled end, a cylindrical member encircling the rings, and diametrically disposed headed adjusting devices fitted to the inner Walls of the cylindrical member at a point adjacent the opposite ends thereof with the head of the adjusting devices engaging the inwardly beveled ends of the rings for efi'ecting inward movement thereof.

In testimony whereof I afiix my signature in presence of two Witnesses.
